Victor and Erik have spent a year planning the perfect midsummer party. The torch placement has been rehearsed. The playlist has been argued about since March. Nothing has been left to chance - until Sonic, the one friend nobody has ever quite figured out, turns up with a bag of small, pineapple-shaped pills, and the best-organized night of the summer becomes gloriously, chemically unplanned.By dawn, ten old friends have said things around the fire that daylight was never meant to hear. What follows is the year the party refuses to stop happening. Erik must decide whether the truth he told at two in the morning can survive an ordinary Tuesday. Karl, carrying a secret only days old, watches his father run out of time. Lea, everyone s little sister, has a letter she hasn t shown anyone. And Clara hydrologist, keeper of the calmest water in the garden begins to suspect that the current she has spent her whole life reading from the bank is finally asking her to get wet.Then, a year later, at a christening with a hundred well-dressed guests, a string quartet, and one unattended industrial cream mixer, the past turns up uninvited in dessert form.Warm, wry, and quietly devastating, Only Good Vibes is a novel about old friendship, late honesty, and the beautiful impossibility of controlling anything that matters.
